Certain “small businesses” may qualify for several valuable tax breaks. But different tax provisions use different size tests.

For instance, a gross receipts test is used to determine eligibility for cash accounting, simplified inventory rules, the completed contract method, relief from UNICAP requirements and exemption from the business interest deduction limitation. This threshold is adjusted for inflation. For 2026, your business may be eligible if its average annual gross receipts for the prior three-year period were $32 million or less.

Contact us to help evaluate your eligibility for these and other tax-saving opportunities based on your business’s structure and operations.

"Client Accounting Services" is one of those phrases that gets used a lot and explained almost never. Here's the short version: it's a full outsourced back office — bookkeeping, AP, payroll, reporting, tech stack, and CFO-level advisory — under one roof, run by CPAs. If you've got clients who've outgrown a part-time bookkeeper, this is the next step.

Happy to walk anyone through it.

Small business owners, beware: Tax identity theft is a costly, ongoing threat. Criminals may file fraudulent returns using a business’s EIN, impersonate executives to steal employee W-2 data, or use forged IRS documents to pose as a business for financial or tax-related activity.

As personal budgets tighten and membership expectations evolve, retaining members has become challenging for many nonprofits. Strong renewal strategies focus on personalized engagement, flexible participation options and clear communication of member impact. Some organizations are also finding success with strategies that specifically address members’ budget concerns, such as installment payment options or tiered memberships. Limited-time incentives can also make renewals more manageable for members. Need help assessing the financial impact of your retention strategy? Let’s connect.

Starting the morning with teamwork and a little dirt on our hands 🌱

Some of the Sheehan team gathered outside the Brightwaters office today for a morning of planting and beautifying the building. A great way to come together, give back to our space, and make the office look even more beautiful for the season ahead.

The American Institute of CPAs (AICPA) has weighed in on the 2026 tax filing season. In a recent letter to the U.S. Senate Finance Committee, it largely commended the IRS’s performance but mentioned that phone services were somewhat inconsistent. The AICPA letter also recommended ways the IRS can improve in future filing seasons. Specific ideas include enlisting the Joint Committee on Taxation to report biannually on the state of the federal tax system, hiring more professionals from the private sector and using taxpayer surveys to assess IRS performance.

If you’re thinking about relocating, don’t choose a new state based only on climate, cost of living or proximity to family. Also review the tax implications.

For example, some states don’t have a personal income tax, and some that do have one offer tax breaks for pension payments, retirement plan distributions and Social Security payments. Also be aware that a state with no personal income tax may impose high property, sales or estate taxes.

Before making a move, contact us to review the potential income, property, sales and estate tax implications. We can help you minimize potential negative tax consequences and make the most of any tax advantages offered by the new state.
